Letters .Patent No. 68,881, dated September 17, 1867.

IMPROVED SHOE-SPIKE.

'ro ALL WHoM 1T MAY ooNcERN:

Be it known that I, ROBERT HUTCHISON, of Newark, in the county of Essex, and State of New Jersey,` have invented, made, and applied to use a certain new and useful Improvement in Shoe-Spikes for ball-players l and others; und I do hereby declare the following to be a full, clear, and exact description of thesaid inven tion, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is an inverted plan of a shoe-sole with my spikes Fitted into it.

Figure 2 is a sectionof one of' said spikes; and

Figure 3 is a section of a slight variation in said spike.

Similar marks of reference denote the same parts. p

The object of my invention is to prevent ball-players slipping upon the gruss or earth where the game is usually played, by zt peculiarly constructed spike, screwed into a metal socket let into the sole of the shoe, andl which spike muy be removed with facility, so as not to inconvenience the wen-rer in walking to or returning from the ball-grounds. This improvement may also be employed to prevent slipping on ice.

My invention consists in a screw-spike, having a polygonal base to the spike portion, so as to give a sufl-` eient bearing upon the surface of the socket into which it is screwed, to prevent the spike being easily bent over or broken; and said polygonal base also receives the key, by means of which the spike is unscrewed` and removed, or again screwed into the metal socket that is employed for its reception in the sole or heel of the shoe.

In the drawing, a represents the sole, and b the heel portion of the boot or shoe; a is a metal socket, secured upon the surface of the sole by the screws or rivets This socket may be let into theleather or` introduced between the lamina of leather, in either the form shown in fig. 2 or inig. 3. The spikec is `formed with n screw portion, 1, to lit the socket c, a point, 2, nt the other end, and a. polygonal base, 3, to the spike point Q, between the screw and spike portions. This polygonal base gives firmness to the spike, and allows for the use of a key,f,'sl1ownin fig. 3, as applied to the spike for screwing or unscrewing the same. This `kcyfis shown separately in Figure 4, and it will be seen to be of a. compact and strong form, adapted to being carried easily in the pocket.

What I claim, and desire to secure by Letters Patent, isv

A screw-spike formed with a point, 2, a screw portion, 1, and a polygonal base, 3, for the reception of the l koy f, in combination with the metallic socket, secured to the sole of the boot or shoe, as and furthe purposes set forth.

In witness whereof I have hereunto set my signature this eleventh day of April, A; D. 1867.

ROBERT HUTGHISON.
